How does Pseudomonas aeruginosa affect the progression of bronchiectasis?

BACKGROUND

Pseudomonas aeruginosa is one of the most common pathogens isolated from respiratory tract specimen in patients with bronchiectasis. It is considered highly responsible for pathogenicity, progression and clinical outcomes of bronchiectasis.

AIMS

To summarize existing evidence on how different factors of Pseudomonas aeruginosa affect the pathogenicity, progression and clinical outcomes of bronchiectasis, so as to provide possible insights for clinical practice and related research in the future.

SOURCES

PubMed was searched for studies pertaining to bronchiectasis and P. aeruginosa published to date, with no specific inclusion or exclusion criteria. Reference lists of retrieved reviews were searched for additional articles.

CONTENT

This review focused on non-cystic fibrosis bronchiectasis and also provided some data on cystic fibrosis when studies in bronchiectasis were limited. We discussed various factors in relation to P. aeruginosa: virulence factors, drug resistance, regulatory systems, genomic diversity and transmission of P. aeruginosa, as well as treatment for P. aeruginosa. Their impacts on bronchiectasis and its management were discussed.

IMPLICATIONS

The impact of P. aeruginosa on bronchiectasis is definite, although conclusions in some aspects are still vague. Faced with the worrying drug-resistance status and treatment bottleneck, individualized management and novel therapies beyond the classic pathway are most likely to be a future trend. To confirm the independent or integrated impact of various factors of P. aeruginosa on bronchiectasis and to figure out all the problems mentioned, larger randomized control trials are truly needed in the future.

National ethics guidance in Sub-Saharan Africa on the collection and use of human biological specimens: a systematic review

BACKGROUND

Ethical and regulatory guidance on the collection and use of human biospecimens (HBS) for research forms an essential component of national health systems in Sub-Saharan Africa (SSA), where rapid advances in genetic- and genomic-based technologies are fueling clinical trials involving HBS and the establishment of large-scale biobanks.

METHODS

An extensive multi-level search for publicly available ethics regulatory guidance was conducted for each SSA country. A second review documented active trials listed in the WHO International Clinical Trials Registry Platform as of January 2015 in which HBS collection was specified in the protocol. Findings were combined to determine the extent to which countries that are study sites for HBS-related research are supported by regulatory guidance language on the collection, use, ownership and storage of biospecimens.

RESULTS

Of the 49 SSA countries, 29 had some form of national ethics guidance, yet only 17 provided language relating to HBS-related research, with specific guidance on consent (14), ownership (6), reuse (10), storage (9), and export/import/transfer (13). Ten countries accounted for 84 % of the active clinical trials involving the collection of HBS in SSA. All except one of these countries were found to have some national guidance in the form of regulations, codes of ethics, and/or standard operating procedures; however, only seven of the ten offered any language specific to HBS.

CONCLUSIONS

Despite the fact that the bulk of registered clinical trials in SSA involving HBS, as well as existing and proposed sites for biorepositories under the H3Africa Initiative, are currently situated in countries with the most complete ethics and regulatory guidance, variability in the regulations themselves may create challenges for planned and future pan-African collaborations and may require legislative action at the national level to revise. Countries in SSA that still lack regulatory guidance on HBS will require extensive health system strengthening in ethics governance before they can be full participants in the modern research enterprise.

Cooperating on Data: The Missing Element in Bringing Real Innovation to Europe's Healthcare Systems

Europe's growing awareness of gaps in its healthcare provision is not being matched by an increase in remedial action - despite the rich transformative potential of new approaches to data. The new availability of data offers policymakers tools that would allow Europe's huge investments in health to be far better spent, by being properly targeted. The result would be far better health for far more Europeans. But that requires a step that most European policymakers have not been ready to take. They need to cooperate so that the data can be shared and its full value realised. This paper explores the potential and the challenges that stand in the way of mobilising health data for wider health benefits. This paper goes on to summarise the results of a survey on how different components of the healthcare sector perceive the opportunities from mobilising data effectively, and the barriers to doing so. The responses demonstrated a widespread genuine will to promote research and innovation, and its take-up, for the betterment of healthcare. There was strong appreciation of the merits of data sharing and readiness - under the right circumstances - to share personal health data for research purposes and to undergo genetic sequencing. This paper also suggests the strategic direction that should influence policy formation. The solution can be found without changing the EU treaties, which already provide an adequate base for cooperation. Properly handled, the problems facing European healthcare can be turned into major assets for Europe and make it easier for citizens to have equal access to high-quality care through the meaningful use of digital innovations.

Sociotechnical systems as a framework for regulatory system design and evaluation: Using Work Domain Analysis to examine a new regulatory system

Like most work systems, the domain of adventure activities has seen a series of serious incidents and subsequent calls to improve regulation. Safety regulation systems aim to promote safety and reduce accidents. However, there is scant evidence they have led to improved safety outcomes. In fact there is some evidence that the poor integration of regulatory system components has led to adverse safety outcomes in some contexts. Despite this, there is an absence of methods for evaluating regulatory and compliance systems. This article argues that sociotechnical systems theory and methods provide a suitable framework for evaluating regulatory systems. This is demonstrated through an analysis of a recently introduced set of adventure activity regulations. Work Domain Analysis (WDA) was used to describe the regulatory system in terms of its functional purposes, values and priority measures, purpose-related functions, object-related processes and cognitive objects. This allowed judgement to be made on the nature of the new regulatory system and on the constraints that may impact its efficacy following implementation. Importantly, the analysis suggests that the new system's functional purpose of ensuring safe activities is not fully supported in terms of the functions and objects available to fulfil them. Potential improvements to the design of the system are discussed along with the implications for regulatory system design and evaluation across the safety critical domains generally.

Making the investment case for national regulatory authorities

Well-functioning national regulatory authorities (NRAs) ensure access to safe, effective, quality-assured, and affordable medical products. However, the benefits of their work are often unseen and difficult to attribute, thereby making NRAs undervalued and under-resourced, particularly in low- and middle-income countries. This paper offers three key arguments NRAs and other stakeholders can use to advocate for greater investment in regulatory systems strengthening-medical products regulation effectively safeguards public health; effective regulation improves health system's efficiency by increasing access to affordable medical products, contributing to universal health coverage; and robust regulation strengthens local pharmaceutical manufacturing and bolsters pharmaceutical trade. NRAs' critical role in health systems is indisputable, yet they need to better promote their value to receive the requisite resources to function effectively.

The regulation project: Tools for engaging the public in the legal regulation of drugs

Lack of legal regulation and oversight of scheduled drugs in Canada has led to an unsafe drug supply responsible for the deaths of tens of thousands. In addition to contributing to the worst unregulated drug poisoning crisis in Canada's history, the policy framework prohibiting non-medical access to certain drugs has exacerbated numerous public health and safety concerns. An alternative approach to prohibition is for government to retake control of the currently illegal drug market through legal regulatory mechanisms. This paper presents the work of an ongoing international collaboration of organizations advocating legal regulation and some of the knowledge translation tools used to educate and engage the public on legal regulation within Canada. In order to encourage thinking and decision-making among stakeholders in a productive way, models of legal regulation for various substances were created as discussion tools to emerge values and considerations supporting different approaches. The models focus on five questions: 1) who has access to drugs; 2) how access is obtained; 3) where drugs can be accessed; 4) how much people can obtain; and 5) where drugs can be consumed. The models were presented to stakeholders in the context of an international meeting on legal regulation, and then adapted to a more "user-friendly" form: a collaborative negotiation-based Regulation Game, which was presented at a workshop in Montréal, Canada. Engaging different stakeholder groups on policy choices of legal regulation revealed initial barriers that we feel more confident can be overcome through creative and innovative tools such as the Regulation Game. Use of the game as a foundation for more traditional focus groups could be effective in reducing barriers to fulsome policy discussions on legal regulation.

Ebola outbreaks: A stress test of the preparedness of medicines regulatory systems for public health crises

In a globalized world, infectious diseases of international concern are inevitable. When they (re-)emerge, the regulatory system works towards mitigating their impact. Ebola outbreaks marked a turning point in regulatory preparedness and efforts led to the accelerated development of therapeutic agents, in a catastrophic environment. However, only one clinical trial determined a vaccine's efficacy. Key lessons were considered and applied thereafter. The collaborative work resulted in the approval of the first therapeutic options against Ebola, a milestone in public health preparedness. The response demonstrated the successful implementation of regulatory mechanisms fostering development, early access and assessment of therapeutic agents, and the flexibility to embrace innovative regulatory solutions. The current system is robust to address health crises and protect global health.

Ontario's health profession regulatory landscape: a mixed-methods study of structures, practices, and perceptions

BACKGROUND

Health profession regulatory colleges in Canada are comprised of public and professional members working collaboratively to regulate a profession and protect the public. Though this general structure has inhered for decades, British Columbia recently amalgamated several colleges into larger agencies that represent multiple professions. This study investigates the landscape of health profession regulation in Ontario with the aim of guiding policymakers, professionals, and the public as they navigate both existing structures and potential changes.

METHODS

Senior-level staff from each of the 26 colleges in Ontario (regulating 30 distinct professions) were invited to participate in a 28-question online survey and semi-structured interviews in 2022. The survey and interviews explored structures, practices, and perceptions within Ontario's health profession regulatory bodies.

RESULTS

Forty-six survey responses were received, with participants representing 22/26 health profession regulators in Ontario. 5 of these participants were engaged in follow-up interviews. Results showed that Ontario colleges range in size, with a mean of 47.4 staff and 16.3 board members (53.8% professional, 46.2% public), that they regulate an average of 8994.6 health professionals, and that they maintain a variety of committees. They receive a minimum of 5 complaints annually and a maximum of 550, with a minimum of 0 and maximum of 25 leading to disciplinary action. Complaints range from sexual assault (< 10% of total complaints) to breach of standards of practice (> 50%). Policy infrastructure is consistent amongst colleges, with most maintaining policies for code of conduct (94.7%) and fewer for speaking and writing engagements (23.7%). Finally, participants felt their colleges were "very effective" in public protection (62.9%), "very ethical" in their activities (68.6%), and with "very functional or functional" (88.8%) councils. 94.2% indicated that a mixture of professional and public members should run councils (the status quo) and 62.9% agreed with the current model of self-regulation.

CONCLUSIONS

Health profession regulatory systems benefit from a current picture of existing regulatory bodies. Input and perceptions from college staff-individuals embedded in the everyday operation of these institutions-should be considered to guide potential changes to the structure of health profession regulation in Ontario.
